New UPS Family from Staco Energy Protects Loads from 10 to 125kVA

June 14, 2011 by Jeff Shepard

Staco Energy Products Co. introduced the FirstLine® P and FirstLine Pl – a family of parallelable, three-phase, online, double-conversion Uninterruptible Power Supplies (UPS) for 10-125kVA applications. True on-line, double-conversion technology is achieved through IGBT and Digital Signal Processor (DSP) control, enabling delivery of a high input power factor of 0.99, and a low input current distortion of less than or equal to 3%. These compact and reliable models are well suited for information technology (IT) applications such as computer rooms, and network closets, as well as broadcast studios, assembly/manufacturing lines, medical facilities, and other applications where a high level of available power are essential.

Up to 8 FirstLine P units (N + 1), and up to 4 FirstLine Pl units (N + 1) can be run in parallel providing redundancy for mission critical applications requiring no additional hardware. All units are hot swappable, for maximum flexibility, availability and expandability. Dual Bus System and Dynamic Dual Bus system configurations provide an efficient and reliable power source. The FirstLine P and Pl requires only front, top or bottom access, so they can be placed against a wall, minimizing its footprint. Battery run times are described as best in class.

The IGBT-based rectifier solid-state technology reduces the impact of the UPS on the local supply and simplifies installation where there is limited power capacity in the form of available electrical supply rating or generator size. Classified as a "Zero Impact Source", the FirstLine P provides a high input power factor of 0.99, a low input current distortion of less than or equal to 3%, and a power walk-in function that ensures progressive rectifier start-up. It also performs as a high performance filter by protecting upstream power supply sources from any harmonics and reactive power generated by the loads power.

FirstLine P models feature an output transformer with galvanic isolation (between the load and the battery supply) to provide greater versatility and installation options. The UPS can be supplied from two separate power sources (main power and a second emergency standby source) which can increase the resilience of single or parallel system configurations.

FirstLine P is intended for applications with input voltage of 480Vac and a range of +15/-20% without battery contribution (+15/-30 in battery mode). Input frequency is 45-65Hz. Progressive rectifier (walk-in) can be configured from 0 to 30 seconds. Delay of progressive start of rectifier (Power Walk-In delay timer) can be configured from 0 to 120 seconds. The entire FirstLine range of products is compatible with capacitive loads such as blade servers, without any reduction in active power, ranging from 0.9 lead to 0.8 lag and up to 0.8 capacitive power, with a low derating equal to 15% of the active power (kW).

FirstLine Pl models can be supplied from two separate power sources (main power and a second emergency standby source) which can increase the resilience of single or parallel system configurations. FirstLine Pl models are intended for applications with input voltage of 208Vac and a range of +20/-20% without battery contribution. Input frequency is 45-65Hz.
